Comparison of Wall Friction Measurements by Jenike

For a silo design, it is very important to understand the friction characteristics of bulk solids with silo walls. This so-called wall friction angles were measured in this study with two different testers: Jenike shear tester and Schulze ...

Thus the greatest change in horizontal stress is near the surface of the bulk solids. Figure 7 shows 16 A theoretical analysis of stresses in silos with vertical walls typical stress profiles for a material with a = 50 and O = 25 . 3. THE SWITCH STRESS Wh
